摘要
南定电厂机组分布式控制系统DCS(DistributedControlSystem)的改造范围包括协调控制、锅炉燃烧器管理、顺序控制、数据采集功能、电气控制系统、汽机的数字式电液调节系统及公用系统,涉及机组几乎所有主、辅机设备的控制和回路控制,I/O点数为3263点,系统点全部能在DCS中进行显示、报警、历史数据分析、控制等功能。改造后以显示器监控取代常规仪表,完善监控覆盖面,适度保留主要参数仪表备用,使运行人员可完全通过显示器和鼠标安全、可靠、高效地监控机组的运行和启停。
The DCS(Distributed Control System) retrofitting of Nanding power station unit relates to almost all master and auxiliary device controls and loop controls,including coordination control system,furnace safety supervisory system,sequential control system,data acquisition system,electrical control system,digital electro,hydraulic control system and public system. Its I/O point number is 3 263,and the system points are all involved in DCS for display,alarm,historical data analysis,control and so on. After retrofitting,monitors replace the conventional instruments,with some key para,meter instruments standing,by,while the monitoring range is expanded. Operators can supervise the unit operation,including start,up and shut,down,via displays and mice safely,reliably and efficiently.
